I Specification of Letters Patent. 7 Patented Mar; 11, 1919.

Application med April 1, 1913. Serial No. 226,094.

Toall whom z'tmay concern Be it known that'I, FRANKLIN P. SPAN4 GLER, a citizen of the United; States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented anew and useful Oil Burner, ofwhich the following is a specification, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon.

This invention relates to the type of oilburner that is designed for converting oil or volatile liquid by means of heat into gas or gaseous vapor to be consumed by means of the burner whereby to obtain heat, the invention having reference more particularly to an oil-burner of the above-mentioned character that is adapted to be used in various types of'stoves or'ranges.

- An object of the invention isto provide an oil-burner which shall'be of simple and inexpensive construction; and which shall not be liable to derangement or to cause trouble inoperation because .of deposits of carbon in the ,oil or gas passages thereof. Another object is to provide an improved oil-burner for stoves, furnaces or ranges which shall be so constructed as to be unitary and adapted to be readily applied to various types of stoves or ranges which may have been constructed for. utilizing coal, wood or other kinds of fuel.

A. further objectyis to provide an improved safety oil-burner which shall be of suchdesign 'as to be strong, self-supporting, adapted for utilizing the grade of oil commonly. known as kerosene which may be cheaply obtained generally throughout the country, and permit .heating and cooking at small cost and without danger or damage or injury dueto explosions. 7

With the above-mentioned and other objects in view, the invention consists in an oil-burner provided with a generator having a broad and fiat bottom and arranged above the oil-burner, and a super-heater arranged between the oil-burner and the generator, the oil-burner being provided with a priming-pan which preferably is rigidly secured to the oil-burner to support it. The invention consists also in an improved supplyinging to the generator. Also, the invention consistsfurther in the novel parts and combinations and arrangements of parts as hereinafter particularly described and further defined in the accompanying claims. 5

Referring to the drawings,+Figure '1 is a perspective view of a cooking-stove or rangeequipped with the new oil-burner as an illustration of the application of the invention to supply heat'forcooking purposes, being one of the various uses to which'the burner may be put; Fig. '2 isa topplan of the oil-burner arranged in the fire-box of the range; Fig. 3 is a vertical central section of the new burner unitarily constructed; Fig. 4 is a fragmentary section. on the line IV-IV on Fig. 3, Fig. 5 is a fragmentary section on the line V-V on Fig. 3; and, Fig. 6 is a bottom plan view of a part of the combined oil-supplying and heating-pipe.

Similar reference characters on the different figures of the drawings. indicate corresponding elements or features'ofconstruction herein referred to in detail.

In the drawings thenumeral 1 indicates a the aperture preferably: being screw I threaded. A' burner-pipe 11 is horizontally.

arranged in the apertures 9 and 10 and extends through the end walls, being preferably screwed intov the aperture 9 or otherbase. A pipe-fitting is connected to one projecting end of the burner-pipe and preferably has'contactwith the outside of the wall 5. When two burners are desired in a range or stove the pipe-fittingis in the form of a T12 and is arranged with the side.neck;.13 thereof vertical; The opposite end of'the burner-pipe 11 has a capl lthereon which preferably is in contact with the outside of .range or cooking-stove and 2 the-rear end of the fire-pot or box having the usual fire- The e'ndwalls 5 and 6 wise rigidly secured to the priming-pan or the wall 6, so thattheiburner-pipe may "be-xx secured in'place, ormorefirmly locked,,by meansfof the IT andthe capQ The upper-- 1 mostportion of the ,wall of the burner-pipe 11 has one or more jet-holesl5}and:16therein. A burner+pipe 17 :is connectedto the T s 12 and has a cap 18 on its end, and the up permost portion ofthe wallof theburnerpipe has one or more'jet-holes 19 and 20 therein. neck or side branch 13 and is supported thereby. A superheater-pipe 22 is horizontally arranged above the burner-pipe 11 and connected at one end to the-elbow and supported thereby, a return L or gooseneck fitting=23c1being connectedto the opposite end of the superheater-pipe so as to extend upwardly and partially over the superheater- 1 e. p nn improved. generatori is provided which comprises a disk-shaped bottom 24 which preferably has a convex under side, 25, ,a circularwall 26 onthe bottom anda top .or cover 27 v :upontthe wall. The wall of the generatorhas a boss 28.:thereon provided with-;an outlet port 29,; the; boss being connected to and .supportedsby the fitting 23 soias to support the generator horizontally with the bottom- 24 abovecthe superheaterpipe 22. The boss 28 preferably has, a bottom extension :30 provided :with an outlet port 31 which 3 in the present case is closed by a plug32. Thergenerator thus-is adapted to be conveniently arranged in an upright heating-stove and permitting the-plug to be transferred to the mainv portionof the, vboss 28 -so that-apipe can be connected to the extension 30if desired. Thelwall26 hasa boss 33 thereon provided withian inlet port 34 soas to be arranged opposite to the port 29, anda supply-pipe 35 is connectedto: the boss and in the present case is arranged horizontally above the burner-pipe 17 to obtain the benefit of the flame from the burner-pipe but is protected-rfrom"excessive heat by an armor or casing 36 which directly serves" the purpose of aspreader for theflame. The supply-pipe35 is inserted through a hole 37 into the wall 2-of the range or, stove and preferably'has a lo ck-nut 38-thereon arranged against. the outside of the wall; in

I in such case the casing36-being in contact with the'inside of the wall and also with the boss 33 tofirmIyVsecure the apparatus which is principally supported by the priming-pan -uponthe fire-grate 8. A feed-pipe 39 is connected with-the -supply pipe;35 and is sup- I "plied swith oi l'from a reservoir 40 through a regulating I valve 41". greater in'diameter than the supply-pipe 35 and hangson thelatter so as toprovide an airspace '42 in the lower porti on of the casing, the ends of the casing preferably havingjnotches 513 and'44: to admit atmospheric ,air thereto, for protecting the under portion of the supplying-pipe from excessive heat to prevent deposits of carbon from the ioil p assfingjthrough the supplyingfpipe, whifle obtainingan advantagefderived by moderately jheating the-oilbeforeit entersthe' generator.

In practical use the'oilfis let into the An elbow 21 is connected to. the

The casing 36 is 24 of the generator is heated. As the oil enters the generator it spreads out thinly upon the bottom 24, and there becoming rapidly heated is, converted into gaseous fluid which flows out through the port 29, and then throughvthe superheater-pipe 22in which it. becomes superheated in its passage to the burner pipes to be ignited as it escapes from the jet-holes. The flame :from the burner-pipe 11 is partially. spread by the suprheater-pipe 22 whichis heated by-the flame, and the flame is further vspread out by the bottom of, the generator, .so'thatan advantageous flame is obtained witha'high degree of heat abovev the generator. The flame from the burnerrpi-pe. l'Z not only-heats the supply-pipe 35 through the casing-36 and theair-chamber 42 'but is spread .out by; the casingsufficiently to be utilized in-the rear portion of the rangeor stove. Having thus .v describedthe invention, what is claimed as .new isf I 3 1. An oil-burner including a generato r' comprising a side wall,- a bottom connected tothesidewall and t-rhavi'ng a convex under side, and fa nip 1 connected to the 1 side lwall, one portion 0 .,.the .side wall: being provided with a projecting supply-port boss, the-opposite portion of the :wall' being provided 7 with a projecting dual ou tletsport' boss.
